PHV Circuit Unit
Basic Principle of PHV
The PHV circuit consists of PHV1P, PHV1N, HV2P and PHV2N, of which, the PHV1P and PHV1N
consist of PW and CW output. The PW output range of PHV1 is ±13V~±85V, and the CW output
range is ±2V~±4V. Only PW output of PHV2 is available, and the output range is ±5V~±85V.
The input of the PW circuit of the 4 PHVs is controlled +12V, which is under the control of PMOS
Q5.The PW output voltage of PHV1P and PHV2P is generated by BOOST circuit. The controlling IC
is TL594, which is frequently adopted by our company. The range of output voltage of PHV2P is
+5V~+85V, so when the output voltage is over than 15V, the input is +12V; and when the output
voltage is lower than 15V, the input is +5V. Both the two inputs are under the control of output
voltage controlling signal. The PW output voltage of PHV1N and PHV2N is generated by
BUCK-BOOST circuit. The controlling IC is MAX1847, which is frequently adopted by our company.
The CW output of PHV1P and PHV1N is generated through linear voltage-stabilizing. The input of
CW circuit of PHV1P is +5V and the chip LT1963 LDO is adopted for the linear voltage-stabilizing;
the input of CW circuit of PHV1N is -5V, and the chip LT1185 LDO is adopted for the linear
voltage-stabilizing. The voltage of CW output is regulated by the output voltage controlling signal.
When the controlling signal is 0.45~2.25V, the corresponding output voltage is ±2V~±4V.
The 4 PHV are all equipped with overvoltage protection, and the overvoltage protection of each
circuit is independent. The overvoltage will not be locked, and the voltage is about 93V when
overvoltage occurs.
The 4 PHV are all equipped with over-current protection. In PW mode, once over-current occurs, all
the 4 PHV PW outputs and ±95V will be switched off, while the CW output is not influenced. The

4D Driving Board
The principle diagram of 4D driving board is shown in figure below. The interface signals of 4D
driving board and main board consist of power, SPI interface signals of ADC and DAC, and the
enabling signal of power module. The interface signals of 4D driving board and transducer
connecting board are: two driving signals A and B, HALL signal and its 5V power supply, and
temperature and angle signals of TEE transducer. 4D driving board mainly implements the following
two functions:
z
Amplifies the command-driven current and generates signals of appropriate power to drive
the transducer to the desired position.
z
As a reserved design, it amplifies the temperature and angle signals of the TEE transducer
and provides data collection channel.

CCFL strip lamps are supplied with high voltage from the inverter, producing different brightness
according to different currents. The principle of the inverter is:
The 12V input of the inverter comes from the main board. The main IC of the inverter drives 4
MOSFETs opening/closing alternatively and puts AC square wave to the primary winding the
transformer. The high-voltage square wave induced by the secondary winding is transformed into
sine wave through LC filtering and drives CCFL strip lamp shining. The switch signal controls the
on/off of the strip lamp by controlling the enabling of main IC. The brightness signal adjusts the
brightness of the strip lamp by controlling the duty cycle of square wave of main IC.
The inverter board is equipped with protection circuits of strip lamp open circuit, overvoltage and
over-current. Protection of strip lamp: whenever any of the strip lamps is open circuit, the protection
circuit will act; over-current protection: when the output current is over-current, the feedback signals
from the strip lamp to main IC will restrain the duty ratio of the square wave to reduce the current for
protection; overvoltage protection: the IC has been configured with the voltage-limiting function to
ensure the output voltage is not too high. The socket J26 connecting to main board is defined as
follows:

Fig 3-35 Power Relation Diagram of Video/Audio Capture Card
Principle of the video capture card is described as follows:
After the video capture card is powered on, EM2860 first resets and communicates with the main
unit, and TVP5150 resets simultaneously. At this moment the system displays the newly found
hardware, namely EM2860.After EM2860 resets, its GPIO1 signal will change and control the reset
of EMP202 through PMOSFET.
After the process is completed, both the BCLK and VCLK have clock signals, and SYNC has cyclic
pulses.
3-73
Principle Description
When the capture software is started, LED pin of EM2860 is pulled high, and green LED in the
board is lit up. The video capture card transmits the video capture configuration in the software to
TVP5150 via I2C bus. The TVP5150 sends channel selecting command to analog switch ADG774
according to the received command, and selects encoding method corresponding to configuration.
TVP5150 converts the input video signals to 8-bit digital signals, and transmits them to EM2860. At
the same time, EMP202 transmits the captured audio signals to EM2860 via serial channel.
EM2860 integrates the received signals and then sends them to PC via USB port.

Principle of the CW Board
The block diagram of CW board is shown as figure below:
Fig 3-36 Principle Diagram of CW board
The hardware block diagram of CW board is shown as the figure above. Echo signals that received
by the phased probe and pencil probe will first be amplified through low-noise-amplifying (LNA)
circuit, then pass through the DEMODULATOR to obtain I, Q signals, and I, Q signals will be
sampled through ADC after being filtered out the useless low-frequency and high-frequency signals.
The sampled signals then will be sent through the interface for beam-forming and so on.
Low-phase noise demodulation clock is provided by the clock distributor circuit.
In addition to echo receiving, CW board is also responsible for pencil probe signal transmitting.
The control signals, as well as the data signals, are communicated with the external through
interfaces

Appendix A Electrical Safety
Inspection
The following electrical safety tests are recommended as part of a comprehensive preventive
maintenance program. They are a proven means of detecting abnormalities that, if undetected,
could prove dangerous to either the patient or the operator. Additional tests may be required
according to local regulations.
All tests can be performed using commercially available safety analyzer test equipment. These
procedures assume the use of a 601PROXL International Safety Analyzer or equivalent safety
analyzer. Other popular testers complying with IEC 60601-1 used in Europe such as Fluke, Metron,
or Gerb may require modifications to the procedure. Follow the instructions of the analyzer
manufacturer.
The consistent use of a safety analyzer as a routine step in closing a repair or upgrade is
emphasized as a mandatory step if an approved agency status is to be maintained. The safety
analyzer also proves to be an excellent troubleshooting tool to detect abnormalities of line voltage
and grounding, as well as total current loads.
